Image doesnt render on animation
While it isn’t entirely clear in your description, my guess is that your image is a reference image or a background image. These images are used to assist with modeling in the viewport and are not part of the final render.

If this is the case, there are a few ways to put an image in your scene. First, you can put an image on a plane using the import images as planes add on, and position the plane where you want it. Or you can use compositing.

Hope this helps!
